Combining time-dependent density functional theory and the SCF approach for accurate core-electron spectra
Marcus Annegarn, Juhan Matthias Kahk, Johannes Lischner
Spectroscopies that probe electronic excitations from core levels into unoccupied orbitals, such as X-ray absorption spectroscopy and electron energy loss spectroscopy, are widely…
Plasmon-induced hot carriers from interband and intraband transitions in large noble metal nanoparticles
Hanwen Jin, Juhan Matthias Kahk, Dimitrios A. Papaconstantopoulos +2
Hot electrons generated from the decay of localized surface plasmons in metallic nanostructures have the potential to transform photocatalysis, photodetection and other optoelectro…
Layer-Resolved Many-Electron Interactions in Delafossite PdCoO2 from Standing-Wave Photoemission Spectroscopy
Qiyang Lu, Henrique Martins, J. Matthias Kahk +7
When a three-dimensional material is constructed by stacking different two-dimensional layers into an ordered structure, new and unique physical properties can emerge. An example i…
Core Electron Binding Energies in Solids from Periodic All-Electron -Self-Consistent-Field Calculations
Juhan Matthias Kahk, Georg S. Michelitsch, Reinhard J. Maurer +2
Theoretical calculations of core electron binding energies are important for aiding the interpretation of experimental core level photoelectron spectra. In previous work, the -S…
Frontier Orbitals and Quasiparticle Energy Levels in Ionic Liquids
J. Matthias Kahk, Ivar Kuusik, Vambola Kisand +2
Room temperature ionic liquids play an important role in many technological applications and a detailed understanding of their frontier molecular orbitals is required to optimize i…
Generation of plasmonic hot carriers from d-bands in metallic nanoparticles
Lara Román Castellanos, Juhan Matthias Kahk, Ortwin Hess +1
We present an approach to master the well-known challenge of calculating the contribution of d-bands to plasmon-induced hot carrier rates in metallic nanoparticles. We generalise t…
